2934.30.23.00 - Antidepressants, tranquilizers and other psychotherapeutic agents

This HTS category, 2934.30.23.00, specifically covers drugs classified as antidepressants, tranquilizers, and other psychotherapeutic agents that contain a phenothiazine ring system in their structure, and are not further fused. These are medicinal preparations designed to treat mental and emotional disorders by influencing neurotransmitter activity in the brain. The classification is precise, focusing on compounds with the defined phenothiazine core, and excludes those where this ring system is part of a larger, more complex fused structure.

This classification distinguishes itself from its sibling category, 2934.30.27.00, which is designated for "Other" phenothiazine-containing compounds. While both fall under the broader "Other" heading within the phenothiazine classification, 2934.30.23.00 is reserved for compounds functioning as psychotherapeutic agents. The sibling category would therefore encompass other non-medicinal uses or phenothiazine derivatives that do not fit the specific therapeutic criteria of antidepressants, tranquilizers, or other psychotherapeutic agents.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification within this heading is dependent on the compound's chemical structure, specifically the presence of the phenothiazine ring system, and its recognized pharmaceutical application as an antidepressant, tranquilizer, or other psychotherapeutic agent. Importers and exporters must verify the specific chemical identity and intended use of the product to ensure correct classification under this code.
